Yep, there are three possible reasons for this not being displayed:
1. PHP buffers may not be full (but can be flushed manually)
2. Web server buffers may not be full (no control but often flushed when
you flush the php buffers)
3. The browser may get the data but not display it.
Like you, I've found generally it works. But not necessarily always.
Now it may be OK with the op if the message only shows 95% of the time
and misses 5% of the customers. I mean - a "please wait" isn't the most
important message in the world :-).
But if he does want it to show up 100% of the time, he should be looking
at the other methods proposed here.
